This creamy blackberry Italian soda is perfect when you want a refreshing treat that feels indulgent but keeps carbs low. It blends fresh fruity flavor with sparkling fizz and a velvety creamy finish making it an easy go-to for a quick pick-me-up or a fancy non-alcoholic beverage for guests.

Ingredients
- Blackberry syrup: is the star adding sweet tang with a deep berry taste make sure to pick fresh or frozen berries that are plump and vibrant
- Sparkling water: brings the refreshing fizz for that classic Italian soda feel select a good quality brand with crisp bubbles
- Heavy cream or coconut cream: gives richness and creaminess to balance the tartness choose full fat cream for best texture or coconut cream for a dairy-free twist
- Fresh blackberries and mint: enhance the presentation and add fresh aromatics pick fully ripe berries for the sweetest flavor and bright green mint leaves
Instructions
- Combine and simmer:
- Place the blackberries water and allulose in a medium saucepan on medium heat. Bring the mixture to a gentle simmer stirring occasionally. Cook until the berries have softened significantly and the liquid thickens about 15 minutes. This concentrates the flavor and creates the base syrup.
- Strain the syrup:
- Carefully pour the mixture through a fine mesh sieve into a bowl pressing gently on the solids to extract all the juice while leaving the seeds behind. This makes for a smooth syrup texture that is lovely in the final drink.
- Build the soda:
- Divide about two tablespoons of the freshly made blackberry syrup between two glasses. Add four ounces of sparkling water to each glass slowly so you keep the bubbles fizzing bright.
- Add cream:
- Top each glass with two ounces of heavy cream or coconut cream. Pour slowly over the back of a spoon or just gently float it on top for a layered creamy effect that swirls beautifully when stirred.
- Garnish and serve:
- Add a few fresh blackberries and sprigs of mint to finish the drink with a fresh burst of color and aroma. Serve immediately and enjoy the refreshing combination of creamy berry sparkle.

I really love how the blackberry syrup captures the essence of fresh berries and how the creamy layer softens the tartness creating a perfect balance. This soda reminds me of summer afternoons with friends where simple ingredients turned into moments worth savoring.
